Disclosed are embodiments of a cask for storing hazardous nuclear material with automatic control and cooling of liquified radiation shielding material flowing between primary and expansion tanks to accommodate for internal temperature changes in the primary tank. The cask contains a container with the hazardous radioactive material that emits radiation. The primary tank surrounds the container and has liquified radiation shielding material. The expansion tank is in fluid communication with the primary tank via a siphon tube and also has liquified radiation shielding material and a gaseous fluid pocket that enables expansion and contraction of the liquified radiation shielding material in both the primary and expansion tanks. The siphon tube enables communication of liquified radiation shielding material between the primary and expansion tanks based upon a temperature change in the liquified radiation shielding material in the primary tank.

An easy-to-construct nuclear reactor shielding facility with robust shielding against ionizing radiation is provided. This nuclear reactor shielding facility is a nuclear reactor shielding facility for shielding a nuclear reactor installed on an installation surface by enclosing the nuclear reactor, and includes: a base structure that is disposed around an outer surface of the nuclear reactor except for the installation surface, and encloses an entire surface of the nuclear reactor except for the installation surface; and a shielding structure that is disposed on an entire surface of the base structure and internal of which is filled with water.

The present invention relates to radiation shielding. In order to provide an improved mobile shielding solution, an interconnectable modular radiation-shielding unit (10) is provided for building a radiation-shielding wall. The interconnectable modular radiation-shielding unit comprises a housing and at least one port. The housing at least partially forms a chamber therein that is configmed to hold an X-ray shielding fluid composition. The at least one port leads through the housing into the chamber and being configmed to receive the X-ray shielding fluid composition. The housing comprises a detachably connectable portion that is configmed to be mechanically connected to a detachably connectable portion of a further interconnectable modular radiation-shielding unit to build the radiation shielding wall.
